YSpecification of Letters'latent. Patented B131'. 14, 1922.

Application filed March 18, 1920. Serial No. 366,727.

To ZZZ whom t may concern.'

Be it known that I, CHARLES PORTER BROOKS, a citizen of the United States, residing at Pleasant Plains, in the county of Independence and State of Arkansas, have invented certain new and useful Improvements in Churns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide a simple and relatively inexpensive churn wherein an efficient agitation of the liquid contents of the receptacle may be produced to insure a prompt separation of the butter,

the interior of the chrun receptacle being unobstructed to permit of the cleansing of the same with facility, and in this connection to provide a construction wherein the operating parts are carried entirely by the lid or cover to the endthat when the latter is displaced the mechanism is withdrawn from the receptacle to permit of free access in the operation of gathering the butter; and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawing, wherein:

Y Figure 1 is a sectional view of a churn constructed in accordance with the invention.

Figure 2 is a transverse sectional view of the same on the plane indicated by the line 2-2 of Figure 1. v

Figure 3 is an inverted plan view of the churn cover showing the adjacent portions of the dashers in section.

The mechanism contemplated by this invention is adapted to be used in connection with a churn receptacle 10 of any suitable form and requiring no special construction other than that it shall be adapted to receive the lid or cover 11 by which the twin dasher spindles 12 are carried, said spindles being arranged substantially in parallelism and each carrying a plurality of blades or wings These dasher spindles are mounted at their upper ends in suitable bearings in the lid or cover and their lower ends in a bearing vbar 14 which is connected with the lid or cover by means of hanger or spacing rods 15 extending to and if desired through the lid or cover as shown, where if desired they may be fitted with adjusting nuts 16 to the end that the bearing bar may be adjusted relative to the plane of the lid or cover to take up any lost motion in the bearingsof the dasher spindles and to permit of the'mounting and dismounting of the latter when required. Near their upper ends the dasher spindles extending through suitable bearings 1( in a bar 18 which serves as a center and also asa set bearing for the spindles 19 of a master gear 2O which is in mesh with pinions 21 carried by the upper ends of the dashers stems respectively to the end that simultaneous rotary movement in a common direction may be communicated to the dashers. The fender bar 18 serves to prevent the hands of the operator from coming accidentally into contact with thegearing in the mampulation of the cover in placing or removing the same, and motion is communicated to the master gear 20 by means of operating mechanism consisting of a driving gear 22,V

having its shaft 23 mounted in suitable bearings 21 on the churn lid or cover and provided with a crank arm 25. Said operating gear meshes with a bevel pinion 26 carried by the shaft 19 of the master gear and is located at the upper side of the lid or cover where it is accessible to the driving gear, also of the beveled type as shown in Figure 1.

It will be noted that when the lid or cover is applied to the churn receptacle the dasher mechanism is suspended in proper position for action upon the liquid contents of the receptacle and owing to the comparatively close relative arrangement of the dashers a violent and effective agitation of the contents of the receptacle is produced with the result that a prompt separation of the butter is effected. When the lid or cover is removed the operating mechanism with the dashers is displaced and the parts thereof are readily accessible for cleansing purposes while the churn receptacle is left entirely unobstructed interiorily to the end that it may be kept in a perfectly sanitary condition.

Vhat is claimed is:

A machine of the class described having a receptacle, a supporting member to rest thereon having a bar spaced below its under surface and suspended therefrom, a driving gear between said supporting member and bar resting on the bar, a dasher having a. spindle mounted in said bar as a bearing and spind1e,said spindle being supported by saidV bearin bar, bolts to suspend the'bearing bar {frornlt e supporting member, and means op-z' erable exteriorly of the receptacle to imparty motion to the driving gear. Y

In testimony whereof I affix my signature in presenceof Vtwo witnesses.
